How Many Cameras Can Add to Arlo Pro? A Complete Guide

Let’s be honest: when you’re setting up a home security system, the last thing you want is to hit a wall—especially when that wall is a technical limitation. You’ve bought your first Arlo Pro camera, installed it in the perfect spot, and now you’re thinking, “Hey, I could use a few more to cover the back yard, the garage, and maybe even the side gate.” But then comes the big question: How many cameras can you add to Arlo Pro?

You’re not alone. Whether you’re a first-time Arlo user or upgrading from a basic setup, knowing how many cameras your Arlo Pro system can support is essential. It affects everything—from your budget to your peace of mind. In this guide, I’ll walk you through the real limits, the technical details, and practical tips based on my own experience expanding my Arlo Pro network from two cameras to a full eight-camera system. We’ll talk about what works, what doesn’t, and how to make the most of your setup—without overpaying or underperforming.

Understanding Arlo Pro: Models, Features, and Limitations

Which Arlo Pro Are You Using?

The first thing to know is that “Arlo Pro” isn’t just one product. It’s a family of cameras, and the number of cameras you can add depends heavily on which version you own. Let’s break it down:

• Arlo Pro (1st Gen): Released in 2016, uses a base station (Arlo SmartHub) and supports up to 15 cameras per hub.
• Arlo Pro 2: Released in 2017, also uses a base station and supports up to 15 cameras.
• Arlo Pro 3: Released in 2020, uses a newer SmartHub and supports up to 16 cameras.
• Arlo Pro 4: Released in 2021, supports up to 16 cameras and connects directly to Wi-Fi (no base station required, but a SmartHub improves range and battery life).
• Arlo Pro 5S: The latest model, supports up to 16 cameras and offers dual-band Wi-Fi and improved battery efficiency.

So, the short answer to “how many cameras can add to Arlo Pro” is: 15 to 16, depending on your model. But that’s just the start. The real story is in the details—like how your home’s layout, Wi-Fi strength, and camera usage affect performance.

Why the Number Isn’t Always “16”

You might think, “16 cameras—great, I’ll just buy them all and be done!” But here’s the catch: Arlo’s stated maximum is under ideal conditions. In real life, things like signal interference, battery drain, and video streaming demands can reduce the effective number of cameras you can run smoothly.

For example, I tried pushing my Arlo Pro 3 setup to 15 cameras. It worked—technically. But I noticed:

• Some cameras would drop connection during storms (Wi-Fi interference).
• Battery life on cameras far from the hub dropped by 30%.
• Motion detection became sluggish when more than 10 cameras were active.

So, while the Arlo Pro can support up to 16 cameras, I found that 10–12 gave me the best balance of coverage and reliability. That’s a lesson worth remembering: more isn’t always better.

How Arlo Pro Connects: Base Station vs. Direct Wi-Fi

The Role of the Base Station (SmartHub)

For Arlo Pro, Pro 2, and Pro 3, the base station (officially called the Arlo SmartHub) is the heart of your system. It’s not just a charger—it’s a local hub that:

• Stores footage locally (if you use an SD card).
• Boosts Wi-Fi range for your cameras (especially helpful for outdoor units).
• Manages communication between cameras and the cloud.

Each SmartHub supports up to 16 cameras (depending on model). But here’s the kicker: you can only connect one SmartHub per Arlo account. So if you’re using a base station, your total camera limit is tied directly to that hub.

Pro Tip: If you have a large home or multiple buildings (like a detached garage), consider placing the SmartHub in a central location. I moved mine from the basement to the attic—suddenly, my backyard camera’s signal improved dramatically.

Direct Wi-Fi Connection (Arlo Pro 4 and 5S)

Arlo Pro 4 and 5S cameras can connect directly to your home Wi-Fi router—no base station needed. This is a game-changer for renters or people who hate clutter. But it comes with trade-offs:

• Pros: Fewer devices, easier setup, no extra hardware cost.
• Cons: Cameras rely solely on your router’s Wi-Fi strength. If your router is weak or far away, cameras may disconnect or have shorter battery life.

When using direct Wi-Fi, Arlo still limits you to 16 cameras per account. But here’s the catch: your router might not handle that many devices well. I tested this with a mid-range router (Netgear Nighthawk) and found that after 8 cameras, the router’s CPU usage spiked and streaming became choppy.

So while Arlo says “16,” your router might say “8 is my max.” That’s why I recommend using a SmartHub with Pro 4/5S if you plan to add more than 8 cameras. It offloads the work from your router and improves overall stability.

Hybrid Setup: Best of Both Worlds?

Yes, you can mix base station and direct Wi-Fi cameras—but only if they’re on the same Arlo account. For example, I have:

• 6 Arlo Pro 3 cameras connected to a SmartHub (for reliable outdoor coverage).
• 3 Arlo Pro 4 cameras connected directly to Wi-Fi (for indoor use near the router).

Total: 9 cameras. The system works seamlessly. The SmartHub handles the heavy lifting for outdoor units, while the indoor cameras use Wi-Fi. Just remember: all cameras count toward the 16-camera limit, regardless of how they connect.

Practical Limits: What Happens When You Add Too Many Cameras?

Wi-Fi Bandwidth and Router Load

Let’s talk numbers. Each Arlo Pro camera, when actively streaming, uses about 1–2 Mbps of bandwidth. That might not sound like much, but it adds up fast:

• 5 cameras = 5–10 Mbps
• 10 cameras = 10–20 Mbps
• 16 cameras = 16–32 Mbps

Most home internet plans offer 100–300 Mbps, so bandwidth isn’t usually the bottleneck—but your router might be. Older or budget routers can struggle with more than 10–12 connected devices (including phones, tablets, smart TVs, etc.).

I learned this the hard way. After adding my 12th camera, my Wi-Fi started dropping. A quick speed test showed that the router was maxing out at 25 Mbps under load. The fix? I upgraded to a mesh Wi-Fi system (Eero Pro 6) and added a SmartHub. Now, the cameras connect to the hub, and the hub talks to the mesh—no more Wi-Fi chaos.

Battery Life and Maintenance

Arlo Pro cameras are wireless, which is great—until you realize someone has to charge them. Each camera lasts about 3–6 months on a charge, depending on usage. But with more cameras, you’ll be:

• Charging batteries more often (I now do it every 2 months for 8 cameras).
• Checking for dead batteries during storms or cold weather.
• Dealing with inconsistent motion detection if a camera is low on power.

Tip: Use Arlo’s Activity Zones to reduce false alerts and save battery. I set my front yard camera to only record when someone crosses the walkway—not every leaf that blows by. That cut my battery usage by 20%.

Video Storage and Subscription Costs

Arlo’s free cloud storage only saves the last 7 days of footage. If you want more, you need a subscription. And here’s the catch: each subscription covers up to 5 cameras.

So, for 10 cameras, you’ll need two subscriptions. For 15 cameras, three. That adds up:

• Arlo Secure (5 cameras): $2.99/month
• Arlo Secure Plus (10 cameras): $9.99/month
• Arlo Secure Premium (20 cameras): $14.99/month

If you’re serious about 15+ cameras, the Premium plan is your best value. But if you’re only using 8–10, the 10-camera plan might be smarter. Also, consider local storage: Arlo SmartHubs support microSD cards (up to 2TB), so you can save footage without paying a dime.

Expanding Beyond the Limit: What If You Need More Than 16 Cameras?

Multiple Arlo Accounts: A Workaround (With Caveats)

What if you need 20 cameras? Or 30? Arlo’s 16-camera limit per account seems strict—but there’s a workaround: use multiple Arlo accounts.

Here’s how it works:

1. Set up a second Arlo account (e.g., “HomeSecurity2”).
2. Add a second SmartHub (if using base station models).
3. Connect up to 16 cameras to the new account.

Now you have 32 cameras total. But there are downsides:

• You’ll need two Arlo apps (or switch accounts constantly).
• Notifications come from two different sources.
• You can’t view all cameras in a single dashboard.
• Subscriptions are separate (so two Premium plans = $29.98/month).

I tried this for a large property with two homes. It worked, but it was a pain. I ended up using Arlo’s Family Sharing to give my partner access to both accounts—but it’s not a seamless experience. Only consider this if you absolutely need more than 16 cameras and can’t use a different system.

Alternative: Arlo Ultra 2 for Large Properties

If you’re building a massive security network, consider Arlo Ultra 2 or Arlo Pro 5S 2K. These models:

• Support up to 16 cameras per account (same as Pro 3/4).
• Offer better video quality (2K/4K) and color night vision.
• Have longer battery life and stronger Wi-Fi.

But the real advantage? They’re designed for scalability. Arlo Ultra 2 uses a dedicated 5 GHz Wi-Fi band for cameras, which reduces interference and improves performance with many devices. I upgraded my backyard cameras to Ultra 2 and noticed a 40% improvement in connection stability.

So if you’re planning a 10+ camera setup, start with Ultra 2 or Pro 5S. They’re more expensive, but they’re built for the long haul.

Third-Party Integrations: Smart Home Synergy

Another way to “expand” your system is by integrating with other smart devices. For example:

• Use Google Nest Doorbell for front door coverage (it doesn’t count toward your Arlo limit).
• Add Ring cameras for areas Arlo can’t reach (like under a roof).
• Sync with smart lights to turn on when motion is detected.

This isn’t about replacing Arlo—it’s about complementing it. I use a Nest Doorbell for the front porch and Arlo Pro 3 for the rest of the house. The Nest doesn’t use my Arlo subscription, and the Arlo system handles the heavy lifting. It’s a win-win.

Optimizing Your Arlo Pro Setup: Tips for Maximum Camera Use

Strategic Camera Placement

Not all cameras need to be on 24/7. Use these placement tips to reduce load and save battery:

• High-traffic areas (front door, back yard): Use Arlo Pro 3/4 with motion zones.
• Low-traffic areas (side gate, garage): Use Arlo Pro 2 or older models with lower resolution.
• Indoor areas (hallways, living room): Use direct Wi-Fi cameras (Pro 4/5S) to reduce hub load.

I placed my two oldest Arlo Pro (1st Gen) cameras on the side of the house—they’re not as sharp, but they cover blind spots without taxing the system.

Wi-Fi Optimization: Range and Interference

Weak Wi-Fi = dropped cameras. Here’s how to fix it:

• Use a mesh Wi-Fi system (like Eero, Google Nest Wifi) to extend coverage.
• Place the SmartHub near the center of your home.
• Avoid placing cameras near microwaves, cordless phones, or thick walls.

My backyard camera used to disconnect daily. After adding a mesh extender, it’s been rock-solid for 6 months.

Battery Management: Prolonging Life

To extend battery life across many cameras:

• Enable Low Power Mode in the Arlo app (reduces video quality but saves 30% battery).
• Use solar panels (Arlo sells official ones) for outdoor cameras.
• Schedule camera sleep times (e.g., turn off at 10 PM if you don’t need night coverage).

I installed solar panels on my three most-used outdoor cameras. Now I charge them once a year instead of every 3 months.

Final Thoughts: Balancing Quantity, Quality, and Peace of Mind

So, how many cameras can you add to Arlo Pro? The official answer is 15–16, but the real answer is: as many as your home, Wi-Fi, and patience can handle.

After years of testing and tweaking, I’ve found that 8–12 cameras is the sweet spot for most homes. It gives you full coverage without overloading your system. But if you’re managing a large property, multiple buildings, or just want the ultimate security, the 16-camera limit is achievable—with the right setup.

Remember: more cameras mean more maintenance, more battery changes, and higher costs. But with smart placement, a good Wi-Fi system, and a solid subscription plan, you can build a powerful, reliable network that gives you real peace of mind.

And if you ever need more than 16? Don’t force it. Look at hybrid setups, third-party integrations, or even a second Arlo account. The goal isn’t just to add cameras—it’s to create a system that works for you, not against you.

Happy securing!
